Do tinned fruits such as pears count towards a portion of fruit for a toddler?

My little girl eats really well, has plenty of fresh fruit (apples, bananas, gs, pineapple, oranges etc) and loads of veg (mived in with sauces and accompanying meals). She loves pears - but it's so hard to buy them ripe or keep them, they're either hard as bullets or soft and starting to go brown. They seem good for about a day! She loves tinned pears with yoghurt for tea - I buy them in g juice (she eats them without the juice anyway) - are they ok for little ones as a fruit portion. We also love the frozen blueberries, defrost a little pot in the fridge and mix with yoghurt for pudding - are these similar in nutrional value to fresh fruit? Thanks
